For what it’s worth---why don’t you just ask them? HAI never had anything to hide, and as far as I am aware, that still holds today. Patrick (the president) has ALWAYS had an open door policy. He WILL take your phone call if you request it. In the past I have given the same advice to people who contact me. This will be the best way to answer your questions.
For the record, and to be upfront---I was the Chief Instructor at HAI for many years before moving on, in 1998. I do not represent them, and have nothing to gain by praising them.
